D-Aspartic Acid is simply one of the two forms of the amino acid known as aspartic acid. There’s also another form called L-aspartic which is unique in comparison to D-Aspartic Acid. For all amino acids, except for glycine, there are two forms which are noted as L- or D-.

This refers to how the molecules react under optical light. L-forms are used for protein synthesis and muscle growth while D-forms are used within the human body for a wide range of processes. The main reason why individuals take this supplement is to boost testosterone levels, either within men who are infertile or athletes who are looking to increase levels for training purposes.

It works by targeting the central region of the brain, causing a release of hormones, known as luteinizing hormone, growth hormone, and follicle-stimulating hormone. Overall, this supplement helps users increase natural levels of testosterone, enhance muscle strength, and support metabolic functioning.

What is D-Aspartic Acid?

As mentioned, D-Aspartic Acid is a non-essential amino acid. This means that it naturally occurs within the human body. It is an alternative form of L-aspartic, which is part of the essential amino acid group. It is a critical amino acid regarding the function of testosterone synthesis in males. Basically, it’s important when managing hormone function, especially for athletes.

D-Aspartic Acid and Testosterone

With regards to testosterone, D-Aspartic Acid is used, not the L-form of aspartic acid. It is found in high quantities within the human pituitary gland and inside the testicles. Once men reach the age of 30, however, their testosterone levels begin to decline.

This can result in more body fat, reduced muscle recovery, and a potential decline in muscle building potential. When testosterone levels are low, individuals often also experience reduce the quality of sleep.

When being studied in Naples, it was found that when birds were given D-Aspartic Acid, their brain reacted by releasing lutenizing hormone. This hormone then travels to the testicles, in order to create testosterone. It’s also believed that D-Aspartic Acid maximizes gonadotrophin, a hormone found in the gonads.

If you are trying to boost testosterone levels in order to improve endurance levels, strength, and libido, a D-Aspartic Acid supplement could help you reach your goals. Now, are the benefits worth the potential risk? Let’s examine how D-Aspartic Acid can positively impact your training efforts.

Benefits of D-Aspartic Acid

Since this amino acid is related to testosterone synthesis, it’s on of the most trusted ingredients when men are looking for some of the following benefits.

Enhanced Muscle Building

One of the main reasons individuals typically want to boost testosterone levels if to increase the rate of muscle building. Since this hormone improves protein production, it aids in building lean muscle mass. Testosterone also stops the production of cortisol, helping to reduce the breakdown of muscle and limited the buildup of abdominal fat.

Elevated Sperm Count

If you are looking to enhance fertility, D-Aspartic Acid could help. By increasing testosterone levels, you actually improve sperm count and motility. This essentially increases your chances of conceiving with your partner.

Increased Energy

Higher levels of testosterone have been linked to increased energy production. When you have higher levels of testosterone, you are able to achieve higher sleep quality, which helps boost energy levels. Testosterone promotes the concentration of red blood cells, helping to deliver oxygen to muscles. As oxygen levels increase, individuals experience higher levels of energy.

Are There Side Effects of D-Aspartic Acid?

Like any supplement that enhances testosterone levels, D-Aspartic Acid could create some potential side effects, such as aggression, acne, increased appetite, increased hair growth, and elevated libido (which some view as a side effect). With that being said, these effects are fairly rare.

When taken as the recommended dose, side effects are not likely to appear. In one study, individuals were given 2,660 mg of D-Aspartic Acid daily over the course of 90 days. This research aimed to increase sperm levels within men who had fertility issues.

Sixty of the men were treated and of those, thirty has asthenozoospermia and the other thirty had oligoasthenozoospermia. Researchers then looked at electrolytes, blood cells, creatine, enzymes, and glucose, finding no abnormalities. It was reported that no dangerous outcomes were observed and that this supplement significantly boost levels of lutenizing hormone.

How Much to Take

Within long-term studies, there have not been any human studies that focus on the use of D-Aspartic Acid. With that being said, manufacturers typically recommend using this supplements for a period of two to four weeks. Always read the label on the supplement you’re taking as potency varies.

Current recommendation tend to be around 3 grams daily. If you are currently taking any medications or suffer from any chronic conditions, please speak with your doctor before your first dose.
